| Tissue Specificity | Widely expressed, with highest levels in heart and skeletal muscle. Isoform 1: Expressed in skeletal muscle (at protein level). Isoform 2: Expressed in skeletal muscle but a lower levels than isoform 1 (at protein level). |
| Function | Catalyzes the hydrolysis of membrane sphingomyelin to form phosphorylcholine and ceramide. It has a relevant role in the homeostasis of membrane sphingolipids, thereby influencing membrane integrity, and endoplasmic reticulum organization and function. May sensitize cells to DNA damage-induced apoptosis. In skeletal muscle, mediates TNF-stimulated oxidant production. |
